vented certain new and useful Improvements in Machines for Cleaning Crude Fuel- Oil, of which the following is a specifica-- tion.

My invention relates to improvements in machines for cleaning crude oil of its dirt,v

and refuse before being passed through the burners for ignition, and the objects are, first in combining two machines into one, thereby reducing space and obtaining a continuous flow of clean oil; second, in forming a chamber in the exterior casing in close proximity to a movable strainer, so that a pressure blast can pass through only a small portion of the periphery of the strainer while being moved past the contained pressure chamber; third in so forming a deflecting plate or brush, within the strainer, and

opposite the contained pressure chamber in the casing, so that the movable strainer 1 passes through the opening formed by these two parts, whereby the pressure can be deflected through and circumferentially on the interior surface of the strainer, thereby cleaning and cutting loose all refuse material; fourth, causing the strainer to be partially, or wholly rotated on its axes, in one or both directions thereby assisting the deflecting brush in cleaning the strainer, and fifth, in so arranging the casing With its contained chambers, with regard to the strainer, that all parts can be cleaned with out being taken apart.

I attain the objects of my invention by illustrations shown in the accompanying drawings, in which Figure l is a vertical elevation, of the entire machine partly in section. Fig. 2 is a plan view of the machine, in part section on line II-II of Fig. 1. Fig. 3 is a side elevation of the interior deflecting brush partly in full and partly infs'ection. Fig.4 is a broken front elevation of the deflecting brush enlarged.

Similar letters refer to similar parts throughout the several views.

The confining cylinders 10 and 11, connecting plates 12 and 13, with lugs 14, 15, 16 and 17 constitute the frame work of the machine. 1

Attached to the top of the cylinders 10 and It are caps 18 and 19 recessed into the cylinder as at 20 d secured by stud bolts 21, and nuts 22.

Centrally located in each cap there 7 is formed a stufling box 23'with agland 24,

held and adjusted in position by stud bolts 25 and nuts 26. v

Passing through gland 24, stuffing box 23, and bearing 26 in the bottom of the cap is a stem 27, having one end squared as at 28, the other end being enlarged as at 29, and secured to the perforated strainer, by any suitable means, preferably by screws 30.

Extending downwardly from the underside of the head 29 and concentric with its center, is a centering teat 31.

To the head 29 is secured the cylindrical Patented Aug. 17, 1915.

strainer 32 which is of smaller diameter than the inner diameter of the confining cylinder, the said strainer is perforated through and overits entire surface by openings 33, except where it rests in its bearings at the top, and bottom of the cylinder. The perforations in these strainers are preferably niade smaller than the openings in-the burner so that any matter which passes through the strainer will also pass through the burner without clogging.

The cylindrical strainer 32, as shown in Fig. 2, is set 0E the center of its confining cylinder 10, (although not absolutely necessary) so that a' portion of its periphery bears against the walls of the chamber 34, which extends beyond the interior wall of the confining cylinder, and forms a port opening for the pressure blast, preferably steam, to act direct against the strainer; and a clean oil chamber 34 to convey the clean oil to its outlet.

By the arrangement shown, the strainer can be rotated in its bearing at the top and bottom of the cylinder, to the right or left a full revolution or more if desired by means of the squared stem.

On the bottom of the casing is formed a boss 35 which extends upwardly and. within the bottom of the casing to a point 36, and within the boss is formed the mlet pas sage 37 for the oil.

Centrallywithin the boss, is secured in any suitable manner a tubular column 38 with perforations 39, and extending upwardly to the underside of the head 29,

or defiectingbrush 44, which bears against grooved as at 49 in order that the strainer may accomplish its work when turned in either direction, but I prefer to recess but one face as shown, such recesses being formed at an angle to the horizontal plane for directing the pressure blast downwardly and circumferentially against the inner surface of'the strainer. Refuse from the surface of the strainer can escape from recess 46 by a passage 50which connects with the incline discharge passage 51 below the strainer, and into which all refuse is discharged.

In describing the operation of the machine each cylinder being a duplicate, it is necessary to follow the course of the oil, and

refuse through one cylinder only to fully understand its working. Therefore referring to the sectional portion of Figs. 1 and 2, the highly heated fuel oil under pressure passes up though the inlet valve 52 to pipe 38, (valve 56 being closed) then through the perforations 39 to the interior of the strainer 32, where particles of solid asphalt, sand, and other refuse, are screened against the strainer on the interior surface. While the collecting of refuse is going on, the clean oil is passing through the strainer, into chamber 34, then by the outlet 53, (see Fig. 2,) to the piping 54, and valve to the burner for ignition. This goes on until the flow of oil is not sufficient to supply the burner. When it then becomes necessary to clean the strainer in the first cylinder and use the second cylinder for keeping up a new supply of clean oil for fuel. In making this pressure to the burner.

is then closed, after which the refuse dischange the inlet valve 56 is opened to the cylinder 11 and theoutlet valve 55 shut off from cylinder 10 and opened to cylinder 11 thus continuing the flow of clean oil under The inlet valve 52 charge valve 57-to the cylinder 10 is opened as well as the steam inlet valve 58. With the introduction of the pressure blast, it forces all material accumulated in the perforations 33 to the recess 46 in the brush 44, part of which refuse is carried downward and outward through the passage 50 into the discharge refuse chamber 51, the balance being carried by the speed of the blast through the openings 49 on the face of the deflecting brush in a circumferential and strainer which is carried downwardly to the inclined discharge passage 51 and outward through valve 7.

The cleaning of the cylinder 10 having been accomplished, all valves are closed to this cylinder, and opened only when desired to use the cylinder in its routine order.v In using these cylinders an expert operator can keep the supply of oil to the burner by the use of one cylinder only, as it takes scarely one half a minute to clean the screen thoroughly, and when the supply of oil is shut off for the purpose of cleaning, there re-.

mains enough oil in the air vessel under pressure between the cleaner, and burner, to last during the process of cleaning, with out any appreciable effect upon the fire. In this case the second cylinder is simply held in reserve in case of accident or to give the first cylinder a rest for inspection.

I am aware that strainers have been used for cleaning crude fuel oil, also a blast directed at the strainer for cleaning the strainer of refuse, and also where the strainer has been cleaned without taking the work apart, I do not wish to confine myself to the exact construcion shown, as changes can be made without departing from the spirit of my invention.
